I found some info on the pin that goes up to the eyebrow board.
Pin Number.....Wire Color..........Reading
1....................Green................12 volt +, when eyebrow switch on
2....................Open.................Open
3....................Black................12 volt +, when eyebrow switch on
4....................Orange or White..12 volt +
5....................Red..................12 volt -
6....................Brown................Communication link
My connector has six pins but only 5 wires. I will check the voltage of the wires going up to the eyebrow unit. Then I can check the wires at the eyebrow unit to see if there might be a break somewhere. Next step after that would be to pull the fridge and see if I can see any breaks in the wire.
